P04.03
V/F frequency
point 1
If P04.00 =1, the user can set V//F curve by P04.03–P04.08 V/F is set to the motor
load.
Note: V1＜V2＜V3, f1＜f2＜f3. If the low-frequency voltage is high,
overtemperature and burning may occur and the overcurrent stall and protection
may occur to the solar pump controller.
Setting range of P04.03: 0.00Hz–P04.05
Setting range of P04.04: 0.0%–110.0% (rated voltage of motor1)
Setting range of P04.05: P04.03–P04.07
Setting range of P04.06: 0.0%–110.0% (rated voltage of motor1)
Setting range of P04.07: P04.05–P02.02(rated frequency of motor1) or P04.05–
P02.16(rated frequency of motor1)
Setting range of P04.08: 0.0%–110.0% (rated voltage of motor1)

This function code is used to compensate the change of the rotation speed caused
by load during compensation SVPWM control to improve the rigidity of the motor.
It can be set to the rated slip frequency of the motor which is counted as below:
△ f=fb-n*p/60 Of which, fb is the rated frequency of the motor, its function code is
P02.02; n is the rated rotating speed of the motor and its function code is P02.03; p
is the pole pair of the motor. 100.0% corresponds to the rated slip frequency △f.
Setting range: 0.0–200.0%
